Evolution of compressional and shear wave velocity with increasing confining pressure was measured through a series of ultrasonic velocity tests. A suite of uniaxial and triaxial tests were conducted to measure...

Experimental study on geothermal systems demonstrate that rock shows more plastic behavior at elevated temperatures, even when...

... logs can measure which are compressional wave velocity (VP) and shear wave velocity (VS). Sonic logs have many applications in geomechanics, petrophysics and seismic (Omnes, 1978; Greenberg and Castagna, 1992; Kumar, 1976). Sometimes, due to financial constraints, only compressional wave velocity (VP...

... in highly heterogeneous formations such as fluvial and lacustrine sedimentary rocks. Acoustic/sonic P-wave velocity (Vp) provides one of the best proxies for formation strength, but it is stress- and frequency-dependent. Vp-strength relationships, therefore, can be very sensitive to experimental conditions...

... interpretation. The P-wave velocity of the thick sand body is reduced after gas bearing. Therefore, it is a common method to make use of the velocity of P-wave in different media to determine whether the formation is gas/water or not. This method determines the depth of the gas/water top by identifying the point...
